Re: [gentoo-user] Re: Combining multiple workstations (multiseat)
I'm hoping to use a Pandaboard ES ARM SoC as the host system in the office where only light web browsing is required. http://www.gentoo.org/proj/en/base/embedded/handbook/?part=4chap=9 I've installed Gentoo on a couple of Beaglebones. Being a source-based distro, ARM support on Gentoo is stellar.IMHO, ARM is slowly replacing x86 and this is a great opportunity for Gentoo to grab some user share. Here's my greatest ever contribution to this list: buy NASDAQ:ARMH. Anyway, it's using DisplayLink on the ARM system that I'm worried about. Linux support at all seems to be a matter of disagreement: http://wiki.gentoo.org/wiki/DisplayLink http://displaylink.org/forum/showthread.php?t=61689 If you have not purchase the panda board yet (Arm A9) there are some new, smoking Arm (A-15) dev boards out that look very keen: http://www.howchip.com/shop/content.php?co_id=ArndaleBoard_en That's a beauty and scheduled for November. http://www.arndaleboard.org http://www.phytec.com/products/system-on-modules/phycore/omap5430/ And of coarse the venerable Samsung Arm Chromebook: http://dev.chromium.org/chromium-os/developer-information-for-chrome-os- devices/samsung-arm-chromebook (highly recommended by Vapier) Nice one.

[gentoo-user] Problems building www-client/uzbl-9999
Since this is a ebuild, I'm not filing a bugzilla bug. Note that www-client/uxbl-2012.05.14 built OK.

[gentoo-user] Re: Unable to catch kernel crash dump
I've been getting a kernel oops for awhile that is worse than ever in 3.11.1. It seems to be related to my XHCI USB port. I followed the instructions here: http://wiki.gentoo.org/wiki/Kernel_Crash_Dumps but /proc/vmcore doesn't exist after I reboot the system after a crash. I did notice that I was getting a lot of white text dumped to the screen against a black background before I followed the instructions in the wiki, but after following them the screen just freezes when it crashes. Does anyone know what I might be doing wrong or how to find out? I've discovered that the crash kernel should automatically boot after a crash and that is not happening. Any idea what could be preventing it? Does the following document look up to date and valid? http://wiki.gentoo.org/wiki/Kernel_Crash_Dumps - Grant

[gentoo-user] Btrfs: how to fix slow sequential write performance?
Greetings fellow Gentooistas, at the moment I am doing some testing and evaluating of Btrfs on my own system. Why? Just because I can and I am curious about it. Because I am doing that for evaluation purpose please don't give advise like go ZFS or something like that, thank you. Kernel is 3.10.7, the file system is on one hard drive only (SATA). And here comes my question: sequential write access seems to be slow as hell, actually something around like 10 Mbyte/s according to dd's output. The same HDD performed under ext4 with around 90 Mbyte/s. Command is something like: dd if=/dev/zero of=file.img bs=1G count=150 Nothing else is running at the time of writing, no scrub/balance on the file system or other process eating up much cpu time. Mount option is relatime only. So is this a well known issue only with this kernel or generally with this file system at the moment? Are there any possible fixes to squeeze better performance out of it or is this unlikely to happen so that I should better take that into account of my evaluation and maybe dump it then? Thanks in advance.

Thanks in advance. How old is the fs? - I am ran into a major slowdown due to COW snapshot fragmentation (VMs on ceph using btrfs) - a known problem. Using that kernel is also giving me an eventual hard lockup if I try and do a recursive defrag (on another system), but the ssd on an apple air defraged fine. btrfs is also seems very sensitive to how full it is. Have you tried a btrfsck? - some errors seem to cause slowdowns as well. BillK

[gentoo-user] Managing multiple systems with identical hardware
I'm trying to reduce the number of systems I spend time managing. My previous plan was to set up multiseat on a small number of systems. Now I'm wondering if it would be better to use multiple systems with identical hardware and manage them in some sort of an optimized way so that each set of identical hardware behaves as much like a single machine as possible for management. I could use small SoC systems so I don't have to worry about sourcing components later. Is there a good tool or framework for this sort of thing? - Grant

I could use small SoC systems so I don't have to worry about sourcing components later. Is there a good tool or framework for this sort of thing? The solution you pick depends heavily on how many of these identical machines you have. For some small-ish number (gut feel tells me up to around 10 or so), you could do what I do for my development vms[2]: - have 1 decent spec'ed machine as the master and buildhost - share /etc/portage/, $PORTDIR, /var/packages and /var/distfiles to all clients from some central location (NFS works really well for this) - for each package you want to have on a client, emerge it on the buildhost with the -b option (create binary packages) - emerge stuff on the clients with the -k (or possibly -K) option to use binary packages. Everything should show up in purple. If anything is a different colour, emerge that package on the buildhost and remerge it on the client. - for awesome street cred geek-points, install clusterssh and do all your clients in parallel[1] As long as you share important directories to each client, things stay consistent. What you essentially achieve is build once-install many times However, and I'm likely to get shot down for this here, I think you *really* need to reconsider whether Gentoo is even what you should be using for this. Put aside emotional attachments to your fav distro and take a long hard critical look at your pain-gain ratio. If all you really need is standard user-type gui stuffs on each client, what is Gentoo really buying you (other than the thrill of watching gcc output scroll by over and over and over) Use gentoo by all means on your central server to get exactly the features you want (Gentoo's strong point), but ona bunch of regular clients... I dunno, Ubuntu or Fedora are hard to beat for that... [1] if you haven't played with clusterssh do yourself a favour and do so. there's something hugely awe-inspiring about typing cssh host1 host2 host3 host4 host5 host6 ... and watching 6 xterms pop up and all 6 run the same commands that you type into the controller window. [2] this sounds like I should take my own advice... but oddly Gentoo is ideal for how I use them. I can upgrade and downgrade almost any app to whatever version the developer says is on prod, and enable/disable USE to get the same feature set, and do it all in 10 minutes. No binary distro lets me do that :-) -- Alan McKinnon alan.mckin...@gmail.com
[gentoo-user] trouble downgrading systemd and virtual/udev
I want to downgrade systemd from 207-r2 to 204 (highest stable).
I currently have virtual/udev-206-r2 installed, which prevents
systemd-204.
OK. So I need to downgrade virtual/udev to 200.
I thought
emerge -1 =virtual/udev-200 =sys-apps/systemd-204
would do it. But this failed (see below) and suggested masking
might help.
So I added package.mask/systemd, which contains
=virtual/udev-201
=sys-apps/systemd-205
and then issued the same emerge as above.
But this also failed (see below).
What incantation do I need?
thanks,
allan

prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously. If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously. You may want to try a larger value of
the --backtrack option, such as --backtrack=30, in order to see if
that will solve this conflict automatically.

[blocks B ] sys-apps/systemd (sys-apps/systemd is blocking

These conflicts are often so confusing that I emerge -C both of the
blocking packages and then re-run the emerge that I really want.
In your particular case, if you actually remove both of those packages
your machine will not be bootable until you successfully emerge the
older versions (obviously) so I strongly recommend using quickpkg to
save both packages before removing them.
Then, if the worst happens and you can't install the older versions
you can re-install the saved binary packages with emerge -K.
Right, thanks. Note that sys-fs/udev is not on my system, the conflict
occurs because portage wants to emerge it. I am trying to downgrade the
virtual udev.
I tried your suggestion as follows
* quickpkg'ed
sys-app/systemd virtual/udev sys-app/gentoo-system-integration
* unmerged all three
* merged the desired virtual/udev version with --nodeps
(it wouldn't work without --nodeps)
* tried to emerge the desired versions of the other two
(without using --nodeps)
This last step fails because it seems (assuming I am reading the emerge
tree output correctly, see below) that dev-libs/lubusbx-1.0.17:1 requires
virtual/udev-206.
But I don't see that version dependence in the ebuild. Moreover this is
the only version of libusbx in the tree so (again assuming I am reading
the tree correctly) this says that gnome 3.6 requires
virtual/udev-206-r2, which seems strange. Indeed, canek has said that
gnome has trouble with systemd-206 (which virtual/udev-206 would bring
it).
So I did the emerge -K you suggested and am back where I started.
Any help would be appreciated.
Another officially unapproved workaround I use when really frustrated
is to bypass emerge completely and do this instead:
#ebuild /usr/portage/sys-apps/systemd/systemd-204.ebuild merge
Sometimes it works :)
I am hoping not to have to do that (or emerge --nodeps).

This system is ~amd64 (I should have said that earlier). Yeah. If you are in ~amd64, why do you want to downgrade systemd? I don't believe there is a virtual/systemd package. Did you mean virtual/udev? Yes, sorry. If so, I would create /etc/portage/package.accept_keywords/systemd and put in it two lines -~sys-apps/systemd -~virtual/udev Correct? No, I thought you were in amd64, not ~amd64. If you are in ~amd64, putting things in /etc/portage/package.keywords should be useless. Mixing amd64 and ~amd64 is not supported; it usually works if you are in amd64, and you only keyword some select packages: that's the way I use GNOME 3.8, soon 3.10, in an otherwise stable system. The other way around (being ~amd64, and trying to force downgrade of some packages) sounds rather convoluted to me. I think it would be rather difficult. You can try; since you are in ~amd64 you *need* to mask the latest versions of both systemd and virtual/udev, the ones you do not want. But I would not be surprised if it doesn't work: if *ALL* the system is ~amd64, the probability of something forcibly pulling the latest versions of *anything* increases dramatically. The block could be impossible to solve. If you are trying to downgrade systemd for the problems related to GNOME and logind in 206, I'm happy to report that version 207 (available since Sep 14) solves everything; at least in my desktop and laptop. You should try it. Regards. -- Canek Peláez Valdés Posgrado en Ciencia e Ingeniería de la Computación Universidad Nacional Autónoma de México
